To provide a magnetization device that can adjust the gap in a radial direction between the magnetization device and a rotor and can prevent an increase in size in the radial direction.SOLUTION: A plurality of magnetization members 18 include a magnetization member position switching mechanism 30 that switches the positions of the plurality of magnetization members 18 such that inner peripheral side ends 18a of the plurality of magnetization members 18 are slidably supported by a cylindrical magnetic member 16 in a direction in which the inner peripheral side ends approach and separate from a rotor 12, and the inner peripheral side ends 18a of the plurality of magnetization members 18 are selectively located between approach positions where the inner peripheral side ends approach the rotor 12 and separated positions where the inner peripheral side ends are separated from the rotor 12. In this way, the magnetization members 18 of the magnetization device can be adjusted in a direction in which the magnetization members approach and separate from the rotor 12 to eliminate a change in a radial direction of the cylindrical magnetic member 16, and thereby an increase in size of the magnetization device in the radial direction of the rotor 12 can be prevented.SELECTED DRAWING: Figure 4 【課題】着磁装置と回転子との径方向の隙間が調整可能であって径方向への大型化が抑制可能な着磁装置を提供する。【解決手段】複数本の着磁部材１８は、複数本の着磁部材１８における内周側端部１８ａが回転子１２に対して接近および離隔する方向に円筒状磁性部材１６に摺動可能に支持され、複数本の着磁部材１８の内周側端部１８ａが回転子１２に対して接近した接近位置と回転子１２から離隔した離隔位置とに選択的に位置されるように、複数本の着磁部材１８の位置を切り換える着磁部材位置切換機構３０を含む。このようにすれば、着磁装置のうち着磁部材１８を回転子１２に対して接近および離隔する方向に調整することで円筒状磁性部材１６の径方向の変化を無くすことができ、回転子１２の径方向への着磁装置の大型化が抑制できる。【選択図】図４
